Herba perennis, glaucescens, e radice longa ac gracili palari enas- 
cens pluricaulis, caulibus erectis vel adscendentibus gracilibus, parum 
ramosis et sparsim foliosis, striato-angulatis, circiter 15 em altis. Folia 
pro rata minus dissecta, petiolata, subbipinnatipartita, segmentorum lobis 
atque lobulis subflabellatim inter se confluentibus, lobulis lanceolato-ob- 
longis, breviter acutis, intermediis latioribus obovatis, ad apicem sub- 
rotundatis mucronulatisque, petiolis basalium subvaginanter dilatatis. 
Flores pallide flavi in racemos terminales pauci- (3—8-) floros, satis 
laxos, folia vix superantes dispositi; bracteae satis conspicuae, lanceo- 
latae usque ad ovato-lanceolatae, integrae vel ad apicem denticulatae, 
apiculatae, pedicellos aequantes, 0,3—0,4 mm longae. Sepala mem- 
branacea et squamoidea, subcordata, magis repanda quam denticulata, 
longe apiculata, decidentia; petalum superius 1,5 cm longum, leviter 
carinatum, in toto subarcuatum, lobis subrepandis, non cristatum, calcari 
fere dimidium totius petali occupante, adscendente, ad apicem rotundato, 
vix subbullato; petalum inferius simile, ad apicem fere rectangulariter 
decurvatum; petala interiora unguiculata, ungue sublineari, lamina 
subobliqua, ad basim truncata lobata, vix subpanduraeformi, ad dorsum 
crista longa, sed humili, usque ad petali basim (?) pertinente ornata; 
staminum superiorum appendix nectariferus satis longus et gracilis, 
adscendens, ad apicem hamatus. Siliqua patens vel subpendula, lineari- 
lanceolata, subteres, subtorulosa, modo leviter crenata, pedicello decur- 
vato, 3 em longa, stylo gracili ad apicem curvato coronata. 
Westamerikanische Wüsten- und Steppenprovinz; Zone 
des Great Basin: Arizona, Canon 2 m, below Pagumpa, 4000’ (M. E. 
Jonef, Pl. of Centr. and South Utah, fl. fr. IV. 1894, no. 5085 in U.S. 
Nat. Herb.!). 
Nota: C. macrorrhizae Fedde valde affinis, sed minus elata radice 
tenuiore, racemis laxioribus, bracteis minoribus, calcari pro rata longiore.
